Specification of Letters Patent. Patented Aug, 16, hglgi'.,

Application led August 9, 1905. Serial No.l 2?3,480.

To all whom-it may concern:

Be it known that I, JOHN W. HILTON, a citizenof the United States, and a resident of the city of Bellevuainthe county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Belting, of which 'thel following is a specification. p

The length of all belting such as cotton, linen, or other vegetable material, and also of leather belting will vary according to the dryness or moistness of the atmosphere in which it is. In lumber mills, and forest districts, and in the mill machinery connectedvvith the great number of oil factories of the companies that obtainloil from the earth and load it Work it and reine it, the belting is usually either under a roof, of a structure whose sides are open'to the ingress of the outer atmosphere, or out in the open with no protection whatever. The same is true as to mills usedfor the manufacture of brick and 'in machinery for many industries carried on in the open air, including many of the farm machines, for agricultural purposes. Damp air or lrain does greatly lengthen the belt, and in the absence of moisture during dry Weather, the belt will greatly contract. Those acquainted with the use of belting know that such changes in the length of the belting greatly interfere with the etliciency of the machinery operated by the belting'. VIf the belt, when dry, is. of the correct length, it will, when dampened o1" Wet, be vtoo long, and will slip on the pulleys and irregularly and feebly operate the mechanism it is employed to work. If the belt, when damp, is of correct tension, then when dry, it has contracted and-is too tight, and either breaks or wears out prematurely.

It is the object of 'my invention to furnish a,belting`which shall be Waterproof, and

' thus not subject to the injurious action-of entire fabric.

.the changes .of Weather, as above set forth.

Another of the principal objects of my invention vis to strengthen the fiber and the yarn'of the belting, and thus strengthen the This addition of strength is made 'without interfering with the necessary ilexibility of the belting. Therefore the advantage of such a change in the belting is obvious. @ther minor advantages will be hereinafter apparent. 'A

I vThe several features of my invention and in the country` the various advantages resulting from their use conjointly or otherwise Will be apparent from the'following description and claims.

In the accompanying drawing I show, conventionally, a section of textile fabric belting, with -descriptive inscription thereon.

I will now proceed todescribe Vmy invention in detail. I will describe the same as applied to cotton belting, premising that the invention Will be the same in relation to belting. made of flax {linen} orotheribers.

I provide aliquid consisting o' asphalt,

mineral rubber and naphtha, or other agent that will dissolve the 'asphalt and mineral rubber and will thereafter dry, I prefer naphtha because it dries quickly. This I apply to the belting. The preferred mode of the application of it to the belting is as follows: I duly soak the belting in it, and

when vthe liquid 'has permeated the goods and coated all of the fibers, land as far as may be, permeated the fibers themselves, I remove the beltingr from the liquid and put it to dry. I find the best results are obtained when the belting soaked in andfcoated With the waterprooli'ng material 'is held under tension While the waterproofing material dries. ble. It is impervious to moisture. Consequently it does not stretch. It becomes a standard and eiicient and most valuable article.

The ordinary advantages of a strong belt are -too obvious to need mention here.' (Ene advantage Vof this added strength is as olis somewhat movable. Hence when the lac- `When dry, the beltlng is flexiy ing or other means of connecting together the belting, so as to make an endless belt, areappled, the kind of lacing must be especially adaptedto grasp much of the belting and in afrm manner. therwise the Woof or' filling of the belting will be pulled.

.out by the lacing. After the belting has been treated by my invention, the Woof is stuck fast or cemented to the Warp, and will not easily or readily yield, or slide upon the Warp. Hence'the fabric requires less complicated means for lacing and will be more` serviceable. This cementing ofr the Woof the case by my invention, obviously confers much .additional strength upon the entire fabric.

i I desire it to be understoodthat the Watereverywhere throughout the belting, as is proofing liquid, consisting of the materials first herein named 1n its application te the ,be'lting is the best Waterproolng'material l have found for obtaining the vbest Water- '5 proof beltiug and for securing the best reslits from the beltiug when in use. hThis materiel tllusapplied prevents the fiber from stretching, adds strength to the liber, as Well as strength to the fibers and to the warp and wool combined. and prevents the belt from being pulled ont at the ends. The belt thereafter requires no belt dressing as 'is now usually the ease.

Mineral rubber is ay name applied t0 a Composition of materia-ls, and derives this name from the fact that it has elasticity andA possesses a high melting' point. It is a manufactured product eoxnlnnlng several 1nlgj'redients. It contains a higli per cent. oli' libere`l ot' the beltinnv as the)i are bent around the pulley do n ot crack. but easily and gently `slonforin to the curve and regain their origmal condition et' st1'a1;,zhtness without 1njury, When they are in that straight part of the belt which is .for the rtime being between the pulleys.

What- I claim as new and desire to secure by Letters Patent, is

1. A belting composed of a textile fabric impregnated with' a waterproof composition, consisting essentially of asphalt, and mine 'al rubber, substantially as and furthe purposes set forth.

2. A belting composed of e textile fabric, the Warp andthe Woof of Whic/h are respeelirely impregnated with a waterproof Composition consisting essentially ol asphalt, and mineral rubber, substantially as and 'for the purposes specified.

3. A beltinn' eoniposed ef a textile fabric, the warp and. the woot of which are respeetirely impregnated with a waterproof counuosilion and the interstiees between said warp und wool filled with said composition, said composition consisting essentially of asphalt-.Rund mineral rubber, substantially as and for the purposes specified.

Ll. helling composed of ay longitudinally strelelmd textile fabric, impregnated with a waterproof eomposition, *consisting essenlially oli' asplnilt,v and mineral rubber, subl tantinlly as and for the purposes speeilied.
